A stack of these on a sunny windowsill will keep a child busy for hours. Every piece is a cylinder of crystal-clear translucent acrylic in a different color, so light passes straight through and puts pools of it on the floor, and holding two together makes a third color nobody expected. They stack and balance and sort like any good block set, but the appeal here is looking through them as much as building with them. Made to sit alongside the other Maison Rue sets, so the wooden blocks and these end up in the same tower soon enough.
